Radionuclide cisternography after head injury.

B D Barnes, J T Hoff

    Archives of Neurology
    |January 1, 1976
    PubMed
    Summary

    Radionuclide cisternography revealed cerebrospinal fluid (CSF) circulation abnormalities in severe head injury patients, particularly those with subdural hematomas. Some obstructions resolved, while others required shunting for improvement.

    Area of Science:

    • Neurosurgery
    • Radiology
    • Neurology

    Background:

    • Severe head injury can disrupt cerebrospinal fluid (CSF) circulation.
    • Subdural hematomas and hygromas are common complications affecting CSF dynamics.

    Purpose of the Study:

    • To evaluate early and late effects of severe head injury on CSF circulation using radionuclide cisternography.
    • To correlate cisternographic findings with the presence of subdural masses and cerebral contusions.

    Main Methods:

    • Thirty-seven patients with severe head injury underwent radionuclide cisternography.
    • Patients were categorized based on the presence of subdural hematomas/hygromas or cerebral contusions.
    • Serial studies were performed on eight patients.
    • Angiography was used to assess for transtentorial herniation.

    Main Results:

    • Abnormal CSF circulation was detected in 23 of 31 patients with subdural masses.
    • Five patients with cerebral contusions without extracerebral masses showed normal cisternography.
    • Serial studies indicated persistent obstruction in one, partial resolution in five, and progressive obstruction in two patients.
    • Angiography suggested transtentorial herniation in 11 patients with cisternal block.

    Conclusions:

    • Radionuclide cisternography is effective in detecting CSF circulation disturbances after severe head injury.
    • Subdural masses are frequently associated with abnormal CSF flow.
    • Shunting can improve outcomes in cases of progressive CSF obstruction.
